显示警告: 警告 org.springframework.web.servlet.PageNotFound - 在 DispatcherServlet 中找不到带有 URI [/Webclient/home] 的 HTTP 请求的映射,名称为“dispatcher”
【问题讨论】:
错误提示 dispatcher-servlet.xml 中没有 /Webclient/home 的映射。您的控制器是否具有上述 URL 的请求映射?您可以发布具有该映射的控制器吗? 谢谢小黄人。我没有在我的控制器中映射 /home @RequestMapping(value = "/home") public String gethome() return "home"; 写了这个。现在它工作正常。 你能接受它作为答案吗? 【参考方案1】:控制器似乎没有 /home 的映射,这就是它失败的原因。请添加并尝试一下。
